Sunan Ibn Majah 3267

It was narrated from Wahb bin Kaisan that he heard ‘Umar bin Abu Salamah say:“I was a boy in the care of the Prophet (ﷺ) and my hand used to wander all over the plate. He said to me: ‘O boy! Say the Name of Allah, eat with your right hand, and eat from what is in front of you.’”
